IMPROVEMENT IN BOBBINS FOR SPINNING, 86C.

Specification forming part of Letters Patent N0. 54,465, dated May 1, 1866.

To all whom t may concern:

Be it known that I, LEVI FERGUSON, of Lowell, in the county of Middlesex and State of Massachusetts, have made a new and useful Improvement in Bobbins, and I do hereby declare the same to be fully described in the following specification and represeilted in the accompanying drawings, of which- Figure l denotes a side view, and Fig. 2 a longitudinal section, of abobbin provided with my invention.

The purpose of the said improvement is to cause the bobbin to t closely to the spindle and prevent the bobbin from sticking thereon at or near the base of such bobbin.

In carrying out my invention I provide the bobbin with four or any other suitable number of slits, running lengthwise of it, and com Inencing a short distance above its base and extending upward two inches (more or less)in the shank or body, the diameter of' the bore of the bobbin where the said slits are made in it being somewhat less than that of that portion of the spindle to be encompassed by such part. The diameter of the bore ofthe bobbin, at or near the upper end ofsuch bore, is equal to that of the spindle where surrounded by such upper part of the bobbin.

In the drawings, a is the shank or body, and b the head ot' the bobbin.

c c cc are the slits, their arrangement being more particularly represented in Fig. 3, which is a cross-section of the bobbin, such section being taken through the slits. These slits enable the partof the bobbin in which they are made to with slits extending through its head and prol vided with an elastic ring, arranged iu a groove in such head.

My improvement precludes all necessity of slitting the bobbin, whereby it is rendered weak and liable to be broken, especially when stepped upon or the bobbin by accident may be dropped or fall upon an object.

I do not claim a spool or bobbin provided with a friction apparatus to hold it to the spindie; nor do I claim a bobbin with slits to eX- tend entirely through its head at its base and to have an encircling expansion-ring applied to such head, such ring being liable to become lost or deranged while the bobbin may be in use.

What I claim as my improvement is- The arrangementofthe slit or slits entirely in the shank or body and above the head ot' the bobbin, substantially as described.

LEVI FERGUSON.
